Abstract
The invention discloses a method for improving the smoke discharge height of a chimney. The method is characterized by comprising the steps of a, setting up a supercharging area at the top cavity of the chimney, and compressing smoke ascending to the supercharging area; and b, setting up a smoke vortex ring generating part above the supercharging area, generating smoke vortex when the smoke compressed in the supercharging area passes through the smoke vortex ring generating part, upwards spraying the smoke out of the chimney and then discharging into atmosphere. An upper fixing plate is arranged in the supercharging area and is used to separate the top cavity of the chimney, a lower movable plate is arranged below the upper fixing plate and moves longitudinally in a reciprocating way to compress the smoke between the upper fixing plate and the lower movable plate, and a center opening is formed on the upper fixing plate to serve as the smoke vortex ring generating part. By adopting the method, the smoke discharge height can be increased to more than two times that of an existing chimney with the same size, thus contributing to improve the urban air environment and achieving good social and economic benefits.
Description
Technical field
The present invention relates to a kind of method that promotes the soot emissions height of chimney.
Background technology
Chimney is the key facility that discharges at present flue dust, is also the important pollution sources of cities and towns ambient atmosphere environment.Although taked reduction dust granules and sulphur removal, except the measure such as nitre, discharged flue dust and contain a large amount of fine dusts and toxic and harmful.In order to prevent the sedimentation around the chimney of these flue dust, cause the local environment serious pollution, often adopt the method for increasing chimney height, flue dust is displaced into higher aerial, utilize the air-flow in high-altitude to accelerate the flue dust diffusion.But due to technology and cost, the construction height of chimney can be restricted, and flue dust also can't be displaced into higher height.In addition, take in addition to improve the method for flue dust flow velocity in chimney, although the method helps to improve the height of release of flue dust, it is subject to the restrictions such as boiler specification, and the turbulence effect while due to flue dust, entering atmosphere, promote soot emissions effect limited highly.
Summary of the invention
Task of the present invention is to solve in prior art the defect that the soot emissions height institute technological means of taking that is used for promoting chimney exists, and a kind of soot emissions method highly that promotes chimney is provided.
Its technical solution is:
A kind of method that promotes the soot emissions height of chimney, comprise the steps:
A sets up anallobar at the top of chimney cavity, and the flue dust that goes upward to anallobar is compressed; Then enter step b,
B sets up flue dust collar vortex generating unit above anallobar, be discharged in atmosphere after the compressed flue dust of anallobar generates the flue dust collar vortex through flue dust collar vortex generating unit, then upwards ejects chimney.
In above-mentioned anallobar, the top fixed head is set, cuts off the top cavity of chimney with the top fixed head, the below of fixed head arranges the moving plate in below up, the moving plate in below moves back and forth in the vertical, and the flue dust that enters between the moving plate in top fixed head and below is compressed; Be provided with up the middle pit of the stomach on fixed head as flue dust collar vortex generating unit.
The moving plate in above-mentioned below is arranged to disc, leaves annular gap between the moving plate in below and inner wall of stack, so that flue dust enters the top of the moving plate in below; Circle is arranged at the middle pit of the stomach of top fixed head, and its diameter is less than or equal to the diameter of the moving plate in below.
The present invention has following useful technique effect:
The present invention can be applied to transform existing chimney and newly-built chimney, in the situation that increase a small amount of cost, more than the height of release of flue dust can being brought up to the twice of existing unidimensional specification chimney, help to improve the cities and towns air ambient, have good economic results in society.
Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is further described:
Figure is the structural principle schematic diagram of a kind of embodiment of installing of the flue dust compression (pressurization) taked in the present invention.
In figure, 1. chimney, 2. moving plate, 3. vertical type transmission bar, 4. top fixed head, 5. drive unit support, 6. drive unit of below.
The specific embodiment
by reference to the accompanying drawings, a kind of flue dust compression (pressurization) device of taking in the present invention, comprise top fixed head 4, the moving plate 2 in below and drive unit 6, the top fixed head cuts off the top cavity of chimney 1, be provided with up the middle pit of the stomach that can generate the flue dust collar vortex on fixed head, drive unit is fixed on the top of top fixed head by drive unit support 5, drive unit is connected with a vertical type transmission bar 3, the vertical type transmission bar is positioned on the axis of the moving plate of top fixed head and below, the lower end of vertical type transmission bar is connected with the moving plate in below, drive unit drives the moving plate in below by the vertical type transmission bar and moves back and forth in the vertical, the flue dust that enters between the moving plate in top fixed head and below is compressed, in compressed flue dust process, the pit of the stomach generates the flue dust collar vortex, the flue dust collar vortex is discharged in atmosphere after upwards ejecting chimney.
A kind of method that promotes the soot emissions height of chimney comprises step:
A sets up anallobar at the top of chimney cavity, and the flue dust that goes upward to anallobar is compressed; Then enter step b,
B sets up flue dust collar vortex generating unit above anallobar, be discharged in atmosphere after the compressed flue dust of anallobar generates the flue dust collar vortex through flue dust collar vortex generating unit, then upwards ejects chimney.
In above-mentioned anallobar, top fixed head 4 is set, cuts off the top cavity of chimney with the top fixed head, the below of fixed head arranges the moving plate 2 in below up, the moving plate in below moves back and forth in the vertical, and the flue dust that enters between the moving plate in top fixed head and below is compressed; Be provided with up the middle pit of the stomach on fixed head as flue dust collar vortex generating unit.
The moving plate in above-mentioned below is arranged to disc, leaves annular gap between the moving plate in below and inner wall of stack, so that flue dust enters the top of the moving plate in below.In the fixed head of top, circle is arranged at the pit of the stomach (hole), and the diameter at the described middle pit of the stomach (hole) is less than or equal to the diameter of the moving plate in below.In the present invention, be up to the flue dust of anallobar from chimney bottom, below moving plate while moving downward, flue dust is able to be filled with between the moving plate of top fixed head and below from the peripheral space of moving plate, below, then moving plate is return moves upward in below, the flue dust that is filled with is compressed, and flue dust is forced to pit of the stomach ejection from the fixed head of top, forms the flue dust collar vortex.
Above-mentioned flue dust collar vortex, namely usually said " smoke ring ".The present invention utilizes the air dynamic behaviour of flue dust collar vortex, makes whole flue dust collar vortex make progress in the long journey process, and flue dust is around the circular section rotation in ring week and be difficult for diffusion, and that flue dust can be carried is higher farther.
The relevant technologies content of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
Need to prove, those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within protection scope of the present invention.
